The "status" command shows "reasoning: none" even if changing it to medium

What version of Codex CLI is running?

0.115.0

What subscription do you have?

Plus

Which model were you using?

gpt-5.4, gpt-5.3-codex

What platform is your computer?

Darwin 24.6.0 arm64 arm

Terminal.app

What issue are you seeing?

When I change reasoning effort to medium inside an active Codex CLI session, Codex confirms the change, but /status still shows reasoning none.

This makes it unclear whether:

1. the reasoning setting is not actually being applied, or
2. /status is displaying the wrong value.

What steps can reproduce the bug?

1. Start Codex CLI:

```bash
codex

1. Check the current status

```bash
/status

1. The output should be like: Model: gpt-5.4 (reasoning none, summaries auto)
2. Change the effort:

```bash
/model medium

1. Codex responds: Reasoning effort set to medium.
2. Check again the status:

```bash
/status

1. Outcome:

Model: gpt-5.4 (reasoning none, summaries auto)

What is the expected behavior?

After setting reasoning effort to medium, /status should show:
gpt-5.4 (reasoning medium, summaries auto)
